+## Redirecting
+
+If you would like to redirect the user to a different route after the completion of an action, you can use the `redirect` helper:
+
+1. Import `redirect` from `@solidjs/router`
+2. Call `redirect` with the route you want to navigate to and throw the response
+
+```tsx {10} title="src/routes/index.tsx"
+import { action, redirect } from "@solidjs/router";
+
+const addPost = action(async (formData: FormData) => {
+	const title = formData.get("title");
+	const response = await fetch("https://my-api.com/posts", {
+		method: "POST",
+		body: JSON.stringify({ title }),
+	});
+	const post = await response.json();
+	throw redirect(`/posts/${post.id}`);
+}, "addPost");
+
+export default function Page() {
+	return (
+		<form action={addPost} method="post">
+			<input name="title" />
+			<button>Add Post</button>
+		</form>
+	);
+}
+```
